LuK conventional flywheel is dynamically balanced to reduce vibration and improve clutch performance. Every component is new - never remanufactured. All parts are engineered and built to original-equipment specifications, including the ring gear and dowel pins.

Bolted to the engine crankshaft and serves as the mounting-surface of the clutch assembly

Acts as a heat sink to dissipate heat from the pressure plate and disc.

Contact between the flywheel and disc will naturally cause hot spots, grooves, thermal cracks and/or frequent concave warpage. Therefore, the flywheel should always be replaced or resurfaced during each clutch system replacement. AMS Automotive understands that some flywheels are virtually impossible to resurface and that equipment plays an important role in the quality of the flywheel surface. AMS does not recommend the use of brake rotor lathes or small tool room lathes. Hot spots are significantly harder than the surrounding flywheel material. Brake rotor and small tool room lathes do not have the required cutting capacity to allow the cutting tool to remove hot spots in a uniform manner. Instead, a flywheel grinder or CNC lathe is used.
